Probability Concepts and Events

The video tutorial covers the probability rules, focusing on the addition and multiplication rules. It explains mutually exclusive events, providing examples like coin tosses and dice throws. The tutorial also details the formula for the probability of the union of two events, emphasizing the importance of understanding when to apply each rule.
